AngularJs event to call after content is loaded

Question

I have a function which I want to call after page content is loaded. I read about $viewContentLoaded and it doesn't work for me. I am looking for something like

document.addEventListener('DOMContentLoaded', function () { 
     //Content goes here 
}, false);

Above call doesn't work for me in AngularJs controller.

Angular < 1.6.X

angular.element(document).ready(function () {
    console.log('page loading completed');
});

Angular >= 1.6.X

angular.element(function () {
    console.log('page loading completed');
});

var myTestApp = angular.module("myTestApp", []); 
myTestApp.controller("myTestController", function($scope, $window) {
$window.onload = function() {
 alert("is called on page load.");
};
});

I found that if you have nested views - $viewContentLoaded gets triggered for every of the nested views. I've created this workaround to find the final $viewContentLoaded. Seems to work alright for setting $window.prerenderReady as required by Prerender (goes into .run() in the main app.js):

// Trigger $window.prerenderReady once page is stable
// Note that since we have nested views - $viewContentLoaded is fired multiple
// times and we need to go around this problem
var viewContentLoads = 0;
var checkReady = function(previousContentLoads) {
  var currentContentLoads = Number(viewContentLoads) + 0; // Create a local copy of the number of loads
  if (previousContentLoads === currentContentLoads) { // Check if we are in a steady state
    $window.prerenderReady = true; // Raise the flag saying we are ready
  } else {
    if ($window.prerenderReady || currentContentLoads > 20) return; // Runaway check
    $timeout(function() {checkReady(currentContentLoads);}, 100); // Wait 100ms and recheck
  }
};
$rootScope.$on('$stateChangeSuccess', function() {
  checkReady(-1); // Changed the state - ready to listen for end of render
});
$rootScope.$on('$viewContentLoaded', function() {
  viewContentLoads ++;
});

I was using {{myFunction()}} in the template but then found another way here using $timeout inside the controller. Thought I'd share it, works great for me.

angular.module('myApp').controller('myCtrl', ['$timeout',
function($timeout) {
var self = this;

self.controllerFunction = function () { alert('controller function');}

$timeout(function () {
    var vanillaFunction = function () { alert('vanilla function'); }();
    self.controllerFunction();
});

}]);

I use setInterval to wait for the content loaded. I hope this can help you to solve that problem.

var $audio = $('#audio');
var src = $audio.attr('src');
var a;
a = window.setInterval(function(){
    src = $audio.attr('src');
    if(src != undefined){
        window.clearInterval(a);
        $('audio').mediaelementplayer({
            audioWidth: '100%'
        });
    }
}, 0);

You can directly call it by adding {{YourFunction()}} after HTML element.
